  abstract = {{P}lants adapt to metal stress by modifying their metabolism including the production of secondary metabolites in plant tissues. {S}uch changes may impact the diversity and functions of plant associated microbial communities. {O}ur study aimed to evaluate the influence of metals on the secondary metabolism of plants and the indirect impact on rhizosphere bacterial communities. {W}e then compared the secondary metabolites of the hyperaccumulator {P}teris vittata {L}. collected from a contaminated mining site to a non-contaminated site in {V}ietnam and identified the discriminant metabolites. {O}ur data showed a significant increase in chlorogenic acid derivatives and {A}-type procyanidin in plant roots at the contaminated site. {W}e hypothesized that the intensive production of these compounds could be part of the antioxidant defense mechanism in response to metals. {I}n parallel, the structure and diversity of bulk soil and rhizosphere communities was studied using high-throughput sequencing. {T}he results showed strong differences in bacterial composition, characterized by the dominance of {P}roteobacteria and {N}itrospira in the contaminated bulk soil, and the enrichment of some potential human pathogens, i.e., {A}cinetobacter, {M}ycobacterium, and {C}upriavidus in {P}. vittata's rhizosphere at the mining site. {O}verall, metal pollution modified the production of {P}. vittata secondary metabolites and altered the diversity and structure of bacterial communities. {F}urther investigations are needed to understand whether the plant recruits specific bacteria to adapt to metal stress.},
